Thanks for your posts @LokeAa and @Jdsenter
As bug fixes and performance improvements tells us nothing, I'm sticking with 44.128.5.38 which seems to work just fine [apart from poor vibration and floors and HR problems]. Unless those are notified as being fixed there wouldn't be any point in introducing other problems.
Incidentally two curious observations.
1) The new firmware available notice in the Fitbit App has disappeared and checking for updates now returns watch is up-to-date, where previously it said there was an update.
Presumably it is downloading the newer version and as that is incomplete the older 128.6. 12 is no longer available - often during the download period, which can be days, the phone battery lasts less long.
2) When the notice will finally reappear in the Fitbit App, it won't indicate what is the new [or the old] version - so if the message hadn't disappeared the fact that there is a second update from mine would not have been detectable in the App.
Lastly they might be aligning the OS to the same level as newer watches about to be announced?
There may be an SDK 6.2 ? announcement soon corresponding to this update.

I updated my Sense last night and did 2 hours of HIIT workouts this morning.
My Sense has always had very poor heart rate monitoring, which I compare to my chest strap heart monitor during workouts.
Today I did notice that I had 160 Fitbit Zone minutes for the workout, which is higher than usual. Hopefully this means the firmware update has improved heart rate tracking for me
I chatted with support yesterday about my sleep log not being correct. They said a new release is coming out and they mentioned 44.128.6.17.
He said just keep syncing every 15 minutes as it is coming out. I tried and did not see any change to the firmware ending in .12 that I have.
I wish Google/ Fitbit would get their act together.
Good Luck

I updated to this new fw release on my sense and verified the fw version with “about sense”. The strange thing is the Fitbit app still keeps showing “fw update available”. I kept updating three times and confirmed it is still the same fw version
I have the latest update and very often the sleep data is not working properly. Please get someone on it, we are relying on Fitbit / Google to get this right!

Thanks for getting back to us @PeterWu and @Albysea.
@PeterWu, have you followed the steps of: Why can't I update my Fitbit device?
Thank you for your comments @Albysea, your feedback is appreciated.
Have a nice day.
Best AnswerSo far my floors are way off, my touch screen doesn't respond at all, and my battery drains much faster. How do I go back a version?

Hi @Elle32 - you can't go back unfortunately, but try sync and then Shutdown from the watch Settings menu. Wait at least 10 seconds before placing on the charger to restart it and charge it.
It may resolve some issues.
Often good to restart the phone to be sure if a good connection too.

The latest firmware update 44.128.6.17 is causing rapid battery drain. My sense just started drawing battery quickly this weekend where I'm having to charge twice a day. I turned off all battery draining features which doesn't help. I've addressed it it with Fitbit and all they offer is 35% off a new device if you pass the warranty period. This reminds me of what Apple did years ago in order to force customers to upgrade. I got my sense in January 2022. The latest generation of the sense and versa don't seem to be much better based on reviews.
Frustrating.

Hi @Dbo1123 - not sure how you detect this old firmware update suddenly causes this problem. There are quite a few other causes, the most notable is the watch is damaged, possibly by water getting in, or issues with syncing and the phone. These need to be investigated as to what the real source of the problem is.
If it gets hot while charging stop immediately the watch is damaged.
If the draining stops when you turn off Bluetooth on all your devices look at that issue.

I'm not having any issues with my Sense. I highly doubt that FitBit intentionally bricked devices just to try to force people into buying a new watch. It's unfortunate that the customer service rep you spoke with did not try to help troubleshoot the problem, but I just don't believe that FitBit is intentionally bricking our watches.
